Boyfriend has been having ear issues for a few months now, he s been on antibiotics and ear drops, nothing seems to work. he s had previous earwax buildup problems which were taken care of via warm olive oil and warm water rinses with a soft bulb. After the ear infections happened, we started getting large pencil eraser size white/black/greyish blockage coming out. When the blockage comes out, he feels better, and everything seems to go away, but its been reaccuring and we re concerned about long-term damage, or what we can do at home to prevent it from returning. We ve heard garlic/teatree oil can help with this problem?
